QNAP TS-251 High Performance NAS for SOHO and Home Users Review
 

The new high-performance TS-251 NAS from QNAP is built upon the Intel Celeron J1800 dual-core processor at 2.4GHz and is able to support on-the-fly video transcoding (thanks to Intel Quick Sync Video Technology), while offering very good transfer rates. While the tested unit was equipped with only 1GB of RAM, there is a 4GB version available too, which also supports running virtual machines.
